Funds

The Federal-aid and other funds used in making these improvements are summarized in table 2. Table 2 shows a small amount of Federal aid for tollroads. This was reported by Georgia in the amount of $1.7 million for a toll bridge which will eventually become free. For free roads, a substantial portion of the construction cost, 32 percent, represented Federal-aid contributions.

As a result of these improvements, some portions of the mileage were totally complete as of June 30, 1957, and no further work will need to be done to make them adequate for 1975 traffic. Other portions were only partially complete; even though they have been opened to traffic, more work will be required after June 30, 1957, to make them adequate for 1975 traffic. These future costs are not included in this report, but are included in the separate report being submitted to the Congress required under section 108 (d) of the Federal-Aid Highway Act of 1956.

Costs

Distributions of the costs of the improvements in the toll and free categories are shown in table 3. The upper and middle portions of this table correspond to those on table 2, reporting distributions by status of completion and by location. The bottom portion of table 3 gives the amount for each of the four cost items: Right-of-way, grading and miscellaneous, surface and base, and structures.
